Ofcom are currently debating what to do with the ailing Channel 4, whose advertising-based business model is sinking.

Should the channel receive a portion of the BBC's £130m-a-year"digital switchover surplus" licence fee money? Should it merge withFive or BBC worldwide, give up on its commitment to publicservice broadcasting, or just resign itself to a fate of "manageddecline"?
